Sports Stars Brazil in children with autism spectrum disorder: A feasibility randomized controlled trial protocol.

BACKGROUND: Autism Spectrum Disorder (ASD) children have lower levels of participation in recreational and sporting activities when compared to their peers. Participation has been defined based on the Family of Participation-Related Constructs (fPRC) which defines participation as including both attendance and involvement, with sense of self, preferences and activity competence related to a child's participation. Modified sports interventions such as Sports Stars can act on physical literacy and some of the fPRCs components. This study aims to assess the feasibility of the Sports Stars Brazil intervention for children with ASD. METHODS: This study will be conducted with 36 participants with ASD aged 6 to 12 years old following the CONSORT for pilot and feasibility recommendation. Participants will be randomly allocated into two groups. Intervention group will receive eight, weekly Sports Stars sessions. Each session will include of sports-focused gross motor activity training, confidence building, sports-education and teamwork development. Study assessments will occur at baseline, immediately post-intervention and 20-weeks post-randomization. First, we will assess process feasibility measures: recruitment, assessment completion, adherence, adverse events and satisfaction. Second, we will investigate the scientific feasibility of the intervention by estimating the effect size and variance at the level of achievement sports-related activity and physical activity participation goals (Goal Attainment Scaling), activity competence (Ignite Challenge, Test of Gross Motor Development-second edition, Physical Literacy Profile Questionnaire, Pediatric Disability Assessment Inventory-Computer Adaptive Test-PEDI-CAT-mobility, 10×5 Sprint Test and Muscle Power Sprint Test), sense of self (PEDI-CAT-responsibility), and overall participation at home, school and community, (Participation and Environment Measure for children and young people, PEM-CY). DISCUSSION: The results of this feasibility study will inform which components are critical to planning and preparing a future RCT study, aiming to ensure that the RCT will be feasible, rigorous and justifiable. TRIAL REGISTRATION: The trial was registered with the Brazilian Registry of Clinical Trials database (ID: RBR-9d5kyq4) on June 15, 2022.

Development of the Gross Motor Function Family Report (GMF-FR) for Children with Cerebral Palsy.

Purpose: To describe the initial steps in the development of a family-completed, modified version of the Gross Motor Function Measure (GMFM-88) to report gross motor function of young people with cerebral palsy in their natural environments. Methods: Development of the Gross Motor Function - Family Report (GMF-FR) was based on expert opinion involving 13 experienced clinicians and researchers, in four steps: (1) item identification to target items that reflect functional gross motor performance; (2) item selection; (3) critical analysis of the items; and (4) item and scoring modification. Results: Several modifications to existing items and scoring were made, including wording changes to optimize ease of families' understanding, the addition of photographs to illustrate all items, changes to the items to enable use of furniture instead of specialized equipment, and modifications to scoring criteria to ensure a focus on functional motor skills. Ultimately, 30 items were selected, and specific testing/scoring instructions were created for each item. Conclusions: GMF-FR is a new family-report tool, based on the GMFM-88. When validated, it can be used as a telehealth outcome measure to capture family-reported functional motor skill performance in home and community environments.

Objectif : décrire les premières étapes de l'élaboration d'une version modifiée de la mesure de la fonction motrice globale (GMFM-88) remplie par la famille pour rendre compte de la fonction motrice globale des jeunes ayant la paralysie cérébrale dans leur environnement naturel. Méthodologie : l'élaboration de l'outil de fonction motrice globale ­ rapport familial (GMF-FR), qui repose sur l'avis d'experts ­ soit 13 cliniciens et chercheurs d'expérience ­, s'est déclinée en quatre étapes : 1) détermination des points, pour cibler ceux qui reflète le rendement de la fonction motrice globale; 2) sélection des points; 3) analyse critique des points et 4) modifications aux points et aux scores. Résultats : les experts ont apporté plusieurs modifications aux points et aux scores en place, y compris de la reformulation pour que les familles comprennent plus facilement, l'ajout de photos pour illustrer tous les points, des changements aux points pour utiliser des meubles plutôt que du matériel spécialisé et la modification des critères des scores afin de se concentrer sur les habiletés motrices fonctionnelles. Au bout du compte, les experts ont retenu 30 points, chacun étant assorti de directives précises sur le test et le score. Conclusions : La mesure GMF-FR est un nouvel outil de déclaration par la famille, inspiré du GMFM-88. Une fois validé, il peut être utilisé comme mesure de résultats en télésanté, afin de saisir le rendement des habiletés motrices fonctionnelles à la maison et dans les environnements communautaires.

Study protocol: functioning curves and trajectories for children and adolescents with cerebral palsy in Brazil - PartiCipa Brazil.

BACKGROUND: Gross motor development curves for children with Cerebral Palsy (CP), grouped by Gross Motor Function Classification System (GMFCS) levels, help health care professionals and parents to understand children's motor function prognosis. Although these curves are widely used in Brazil to guide clinical decision-making, they were developed with Canadian children with CP. Little is known about how these patterns evolve in children and adolescents with CP in low-income countries like Brazil. The PARTICIPA BRAZIL aims to: (i) to identify and draw a profile of functioning and disability of Brazilian children and adolescents with CP by classifying them, for descriptive purposes, with all five valid and reliable functional classifications systems (gross motor function, manual ability, communication function, visual and eating and drinking abilities); (ii) to create longitudinal trajectories capturing the mobility capacity of Brazilian children and adolescents with CP for each level of the GMFCS; (iii) to document longitudinal trajectories in the performance of activities and participation of Brazilian children and adolescents with CP across two functional classification systems: GMFCS and MACS (Manual Abilities Classification System); (iv) to document longitudinal trajectories of neuromusculoskeletal and movement-related functions and exercise tolerance functions of Brazilian children and adolescents with CP for each level of the GMFCS; and (v) to explore interrelationships among all ICF framework components and the five functional classification systems in Brazilian children and adolescents with CP. METHODS: We propose a multi-center, longitudinal, prospective cohort study with 750 Brazilian children and adolescents with CP from across the country. Participants will be classified according to five functional classification systems. Contextual factors, activity and participation, and body functions will be evaluated longitudinally and prospectively for four years. Nonlinear mixed-effects models for each of the five GMFCS and MACS levels will be created using test scores over time to create prognosis curves. To explore the interrelationships among ICF components, a multiple linear regression will be performed. DISCUSSION: The findings from this study will describe the level and nature of activities and levels of participation of children and youth with CP in Brazil. This will support evidence-based public policies to improve care to this population from childhood to adulthood, based on their prognosis.

Cardiorespiratory and metabolic responses and reference equation validation to predict peak oxygen uptake for the incremental shuttle waking test in adolescent boys.

BACKGROUND: Previous studies speculated that the Incremental Shuttle Walking Test (ISWT) is a maximal test in children and adolescents, however comparison between ISWT with cardiopulmonary exercise test has not yet performed. Furthermore, there is no regression equation available in the current literature to predict oxygen peak consumption (VO2 peak) in this population. This study aimed to assesses and correlate the cardiorespiratory responses of the ISWT with the cardiopulmonary exercise (CEPT) and to develop and validate a regression equation to predict VO2 peak in healthy sedentary adolescent boys. METHODS: Forty-one participants were included in the study. In the first stage, the VO2 peak, respiratory exchange ratio (R peak), heart rate max (HR max) and percentage of predicted HR max (% predicted HR max) were evaluated in CEPT and ISWT (n = 26). Second, an equation was developed (n = 29) to predict VO2 peak. In both phases, the VO2 peak, respiratory exchange ratio R and hearth rate (HR) were evaluated. In the third stage, the validation equation was performed by another 12 participants. RESULTS: Similar results in VO2 peak (P>0.05), R peak (P>0.05) and predicted maximum HR (P>0.05) were obtained between the ISWT and CEPT. Both tests showed moderate significant correlations of VO2 peak (r = 0.44, P = 0.002) e R peak (r = -0.53, P < 0.01), as well as the agreement of these measurements by Bland-Altman analysis (VO2 peak, bias = -0.13; R peak, bias = 0.0). Distance walked was the variable that explained 42.5% (R2 = 0.425, p = 0.0001) of the variance in VO2 peak. The equation was VO2 peak (predicted) = 20.94 + (0.02 x distance walked). The results obtained by the equation were not significantly different compared to the values obtained by the gas analyzer and the Bland-Altman analysis showed agreement (bias = 1.6). CONCLUSION: The ISWT produced maximal cardiorespiratory responses comparable to the CEPT, and the developed equation showed viability for the prediction of VO2 peak in healthy sedentary adolescent boys.

Association between obesity-related biomarkers and cognitive and motor development in infants.

BACKGROUND: This study aimed to verify the association between obesity-related biomarkers and cognitive and motor development in infants between 6 and 24 months of age. METHODS: A cross-sectional study was conducted with 50 infants and plasma levels of leptin, adiponectin, resistin, soluble tumor necrosis factor receptors 1 and 2 (sTNFR1 and sTNFR2), chemokines, brain-derived neurotrophic factor (BDNF), serum cortisol and redox status were measured. The Bayley-III test was utilized to evaluate cognitive and motor development, and multiple linear stepwise regression models were performed to verify the association between selected biomarkers and cognitive and motor development. RESULTS: A significant association was found among plasma leptin and sTNFR1 levels with cognitive composite scores, and these two independents variables together explained 37% of the variability of cognitive composite scores (p=0.001). Only plasma sTNFR1 levels were associated and explained 24% of the variability of motor composite scores (p=0.003). CONCLUSIONS: Plasma levels of sTNFR1 were associated with the increase in cognitive and motor development scores in infants between 6 and 24 months of age through a mechanism not directly related to excess body weight. Moreover, increase in plasma levels of leptin reduced the cognitive development in this age range.

Inserção de alunos com paralisia cerebral no ensino regular em Betim, MG / Students with cerebral palsy folowing regular schools in Betim, MG, Brazil

A proposta deste estudo descritivo foi identificar o perfil de professores de crianças com paralisia cerebral inseridas no ensino regular, na cidade de Betim, MG. Trinta e um professores participaram do estudo e responderam a um questionário contendo respostas simples. Apenas 42% dos professores apresentaram formação no ensino superior; 77,41% apresentaram mais de cinco anos de experiência em Educação Inclusiva; 71% afirmaram que o desempenho dessas crianças não estava compatível com o período escolar em que estavam inseridas; 16% dos professores recebiam ajuda de especialista; e 77% julgaram necessária melhor formação técnica da equipe das escolas. Concluiu-se que, segundo os professores, a inclusão do aluno com paralisia cerebral no ensino regular não garantiu a mudança de paradigma. Para uma efetiva inclusão escolar do aluno com paralisia cerebral no ensino regular é necessária a promoção de mudanças na prática pedagógica e na organização da estrutura escolar.

The aim of this descriptive study was to identity the profile of the teachers of students with cerebral palsy attending the regular education system in Betim, MG, Brazil. Thirty-one female teachers took part in the study and answered a questionnaire containing simple guidelines. Only 42% of the teachers had higher education; 77,41% had more than five years of experience in the school inclusion field; 71% claimed that the performance of these children was not compatible with the grade they were enrolled in; only 16% received specialized support; and for 77%, better technical training program for the school staff is crucial. The inclusion of students with cerebral palsy in the regular educational system did not cause a paradigm shift. To make sure that students with cerebral palsy will effectively be included in the regular educational environment, changes in the pedagogical practice and in the school organizational structure are urgent.

The effects of foot position on the performance of the sit-to-stand movement with chronic stroke subjects.

OBJECTIVE: To investigate the effects of different foot positions during the sit-to-stand (STS) movements with stroke subjects. DESIGN: Cross-sectional. SETTING: Research laboratory. PARTICIPANTS: Twelve chronic stroke subjects (N=12). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Differential latency and electromyography (EMG) activity of the tibialis anterior, soleus, quadriceps, and hamstring muscles of the affected leg as well as the movement time, time of seat-off, weight symmetry, and rising index were obtained while the subjects performed the STS movements by using 4 different strategies: spontaneous; symmetric; asymmetric-1, with the affected foot behind; and asymmetric-2, with the unaffected foot behind. RESULTS: Compared with the spontaneous strategy, the soleus showed the greatest differential latency in the asymmetric-2 strategy, the hamstrings had lower EMG activity in the symmetric strategy, and the movement time was greater in the asymmetric strategies. CONCLUSIONS: The asymmetric 2 strategy appeared to be the least favorable, whereas the spontaneous and the symmetric strategies appeared to be more favorable in improving the STS performance. Based on these findings, allowing the subjects to adopt the spontaneous strategy or training of the symmetric strategy could result in greater benefits for subjects with higher chronicity and higher functional levels, such as those evaluated in the present study.
